## TL;DR

Lindy is an assistant. Parabola is a production process.

- **Scale of the work:** Lindy suits personal and GTM tasks — email triage, CRM hygiene. Parabola is built for operational data volume.
- **What runs each time:** Parabola executes logic fixed at build time. Agent tools re-reason per run, so behaviour can drift.
- **Visibility:** Every Parabola step shows its input, logic, and output, with row-level tracing.
- **Where Lindy genuinely wins:** Lightweight AI agents for email, CRM hygiene, and personal productivity.
- **Bottom line:** Pick Lindy to take small recurring tasks off your plate. Pick [Parabola](/) when the process is business-critical and has to be identical every run.

## Drift is the thing to watch

An agent that works out its approach each time it runs is genuinely useful when the task is loosely defined. The problem in finance and operations is that you find out about drift from the output — a number that looks wrong, a row that got handled differently than last month — rather than from the process itself.

Parabola avoids that by fixing the logic at build time. AI is still used where it earns its place: import steps absorb the variance in how files and documents arrive, and a step can call a model where the logic genuinely needs interpretation. But judgment is scoped to the steps that need it, and everything around it is the same on run 1 and run 500.

## Parabola vs. Lindy at a glance

| Dimension | Parabola | Lindy |
| --- | --- | --- |
| Typical scope | Recurring operational processes over business datasets | Personal and GTM tasks: email, CRM hygiene |
| Consistency | Fixed logic; the same input produces the same result | Re-reasoned per run, so behaviour can vary |
| Visibility | Step-level input, logic, and output, plus row-level tracing | Output-level |
| Data volume | Built for batch operations at scale | Task-shaped work |
| Output | An Artifact — an interactive, shareable app built from the Flow's data | Actions taken in your tools |

## Which one is right for your team

Choose Lindy for assistant-shaped work close to an individual or a GTM workflow.

Choose [Parabola](/) when the process belongs to the business, runs over real data volume, and someone will eventually need to explain exactly what it did.
